Description
The Bel xRAH-05BT50 is part of the low cost non-isolated dc/dc converter series. The converter is designed
specifically to provide bus termination voltage in application such as DDR (double data rate) memory where the
bus termination voltage must closely track the I/O bus voltage. The converter accepts a reference input and
programs its output voltage to 50% of the reference. The modules use a SMD or vertical mount package for
ease of layout and space savings.
